Can you replace with syn trans fluid when you change it (mix it) or do you need to flush the entire system?

I still have set to see the need for syn trans fluid, I use the cheapo Dex III and change it every 10K... trans works great and has nearly 80K mi with no TqMgt present.

That money is better spent elsewhere IMO.

:word: From what I've heard, the 4l60e was pretty closely designed around the Dex III fluid, which to me makes it a bad idea to switch to something with different properties.

Oh yeah also, Syn makes the 4L60E slip too. I'll assume you're running that or the ol' 700-R4. lol

It costs me about $5 to drain and fill my pan where Syn is like $5/qt! Too much IMO as I change it so often.
